Adhesive used for fluorine material?
There are many kinds of fluorine property materials. Teflon,one of them, is typical of difficult to adhere to. Strong alkaline (water-soluble Calcium Oxide Liquid) process or Plasma process is required before using adhesive. If you want to glue this kind of material, please consult professional staff.
This question depends on how much degree should the adhesive resist? Ployimide, the best heat-resistant one in organic based adhesive series, can resist 300 degree heat.
But if the degree is over 300, you should choose inorganic based adhesive.
Yes. Epoxy adhesive can be used on wetted surface. It is also called as "under water adhesive", which means this kind of product can be used even in the water.
Adhesive used between metal board and reinforced concrete board? And what matters need attention?
All kinds of adhesive belong to Type one. SHARPIE HENSEI series, SHARPIE SILICONE series, SHARPIE URETHANE series all can be used. There exists a big different expansion rate between metal and reinforce concrete, the power to peel off them should be used evenly.
And the apply method is also very important. You must pay attention to how much quantity should be used. We recommend using primer before using adhesive/
Adhesive used between nylon components to the wood? And what matters need attention?
Epoxy based series are recommended. Through improving surface toughness (use sandpaper to scarp the surface of nylon, for example), the adhesion can get improved.
And wood should be in dry state, but not overdrying. Both moisture and overdry have the negative influences to adhesion.
Replace solvent based adhesive with water based adhesive. What matters need attention?
Considering pro-environment and safety, water based adhesive will replace solvent based adhesive someday. However, water based adhesive has its own advantages, the volatilizing speed is much lower，so constructor should pay attention to the required time and control the temperature variation. Moreover, water based adhesive freezes at low temperature. The water resistant is also not as good as solvent based adhesive, test prior to application is recommended.
It is difficult to answer. Even the natural adhesive extracted from animals will affect our health. In some extent, there is no adhesive totally harmless to people. But in modern age, adhesive exist everywhere. What we can do is use the right adhesive according to the place.
It is worth to note that Formalin is nearly not being used. Other harmful substance (like Toluene, Xylene, etc) are much less being used than before.
